SPECIFICATION forming part of Letters Patent No. 416,955, datedDecemberlO, 1889.

' Application filed April 9, 1889. Serial No. 306,544. (No model.)

T0 at whom it may concern;

Be it known that I, DWIGHT H. SCOTT, of Flora, in the county of CharlesMix and Territory of Dakota, have invented a new and useful TensionDevice for Wire Fences, of which the following is a full, clear, andexact description. p

My invention relates to a tension device for wire fences, and has forits object to provide a means for expeditiously taking up the slack inwire fences and retaining the said wire under tension; and a furtherobject of the invention is to provide such a device of simple anddurable construction.

The inventionconsists in the novel construction and combination of theseveral parts, as will be hereinafter more fully se Reference is to behad to the accompanying drawings, forming a part of this specification,in which similar figures of reference indicate corresponding parts inall the views.

Figure 1 is a front elevation of the device. Fig. 2 is a section on line.90 0c of Fig. 1. Fig. 3 is a plan View of the device, illustrating thewire as wound around the device, but not secured thereto; and Fig. 4 isa similar view sition to be left upon the wire.

The device is constructed substantially in, the form of a spool,comprising a tubular body 10, provided at one end with an annular flange11 and a diametrical slot 12, extending through the flange and the bodyadjacent to said flange, as best illustrated in Figs. 2

a series of teeth 13 are produced, which teeth are inclined laterallyand inwardly over the body, as illustrated in Figs. 3 and 4:.

The opening in the body 10 at the end carrying the teeth 13 isrectangular, as shown at 14 in Fig. 2, to receive the end of any desiredform of wrench, the preferred form of wrench, however, being a crank-armhaving one extremity rectangular to enter the equiva lent opening l tofthe device. The rectangular part of the opening is made to terminate ator near the center of the body to prevent the inserted wrench orcrank-arm from volved until the wire is wound thereon sufficiently totake up the slack. The device rotated in a direction opposite to that in6c which the teeth are inclined, and when sufficient tension has beenexerted upon the wire the said wire is made to engage-with the innercurved surface of one of the teeth, as illustrated in Fig. 4, and as thetendency of the coil upon the body is to turn the said body in thedirection of the slant of the teeth the tension of the coil serves toeffectually bind the tooth engaged to the strand of wire with which itengages. It is evident that as the teeth 13 may be placed very closetogether the wire may be drawn only a quarter of an inch, if .sodesired.

Having thus described my invention, I claiin as new and desire to securebyLetters Patent- 1. As an improved article of manufacture, a tensiondevice for wire fences, comprising a tubular body having a flange atoneend, a diametrical slot extending through the said body at said flangedend, and a series of teeth radiating from the opposite end of the bodyand inwardly and laterally inclined over the body, substantially asshown and described.

2. As an improved article of manufacture, a tension device for wirefences, comprising a tubular body 10, one'sectionof the bore of which isrectangular, said body being provided at one end with an annular flangeand a diainetrical slot extending through the said flange, and withhook-like teeth radiating go from the opposite end, laterally andinwardly inclined over the body, substantially as and for the purposespecified.
